急性心肌梗塞早期Q-Tc离散度分析

Analysis of early QTc dispersion in patients with acute myocardial infarction

回顾性分析５７例心肌梗塞（ＭＩ）患者ＱＴｃ离散度，结果提示：急性心肌梗塞（ＡＭＩ）急性期发生严重室性心律失常者早期ＱＴｃ离散度（ＱＴｃｄ）＞未发生上述心律失常者，说明ＱＴｃｄ可能作为ＡＭＴ预后危险的指标之一。

The QTc dispersion of 57 patients with myocardial infarction(MI) were reviewed. The results suggest: the early QTc dispersion of serious ventricular arrhythmia in the acute phase of AMI is higher than those without arrhythmia. So QTcd may be one of the prognostic indications of AMI.
